Question

A satellite on a Low Earth Orbit is flying with a speed of 7.65 km/s. The vertical component of the Earth's magnetic field is 35.3 μT at the current location of the satellite. What is the maximum possible EMF induced between the tips of the solar panels, if the span of the panels is 10.8 m?

Answer 1

2.92 Volts

Step-by-step explanation:

v = speed of the satellite on a low earth orbit = 7.65 km/s = 7650 m/s

B = earth's magnetic field = 35.3 x 10⁻⁶ T

L = length of panel = 10.8 m

E = Induced emf between the tips of the solar panel

Induced emf between the tips of the solar panel is given as

E = B L v

E = (35.3 x 10⁻⁶) (10.8) (7650)

E = 2.92 Volts
